SOLE-TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 469,720, dated March 1,1892. Application filed F ruary 24, 1891. Serial No. 382,496. (Nomodel.)

To all whom it may concern.-

Be it known that I, JAMES H. REED, of Lynn, in the county of Essex,State of Massachusetts, have invented certain new and usefulImprovements in Machines for Cutting and Ohainfering Shoe-Soles, ofwhich the following is a description sufficiently full, clear, and exactto enable any person skilled in the art or science to which saidinvention appertains to make and use the same, reference being had tothe accompanying drawings, forming part of this specification, in whichFigure 1 is a front elevation of my improved machine; Fig. 2, a top planview of the rotary cutter-head, fixed guide-cap, and adjustingmechanism; Fig. 3, an elevation showing the inner side of thecutter-head; Fig. 4:, a like view of the opposite side; Fig. 5, an endelevation of the fleshing or chainfering cutter-head; Fig. 6, a verticallongitudinal section of the same with the knives removed; Fig. 7, aperspective View of one of the chamfering-knives, and Fig. 8 acrosssection of the pattern with the sole-stock in position thereon.Fig. 9 shows an enlarged view of the cutter-head for feather-edging thesole.

Like letters and figures of reference. indicate corresponding parts inthe different figures of the drawings.

My invention relates especially to machines for cutting shoe-soles bypattern and chamfering the same; and it consists in certain novelfeatures hereinafter fullyset forth and claimed, the object being toproduce a sim pier, cheaper, and more effective device of this characterthan is now in ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation.

In the drawings, A represents the body of the machine, which comprisesastandard supported by legs 6 and provided with a horizontal head d. Onsaid head two journalboxes f are mounted, in which a horizontal shaft gis journaled. At the rear of the standard a horizontal shaft h ismounted, bearing a loose pulley j and fast pulley 7 connected by a belt7a with any suitable source of power.

On the opposite end of said shaft a pulley m v is mounted.

A suction fan-blower B, of suitable construction, is supported by abracket 19, mounted on the standard, anda pulley on the shaft q of saidblower is connected by a belt I' with the pulley m. Pipes 25, leading tothe blower, are provided with semicircular heads '0, which partiallyinc-lose the ends of the shaft g outside the bearings f. Said heads aredesigned to collect the dust and chips from the leather which are drawninto the mouths to of the pipest by the blower and ejected through itsdischarge-pipe m. The shaft g is provided centrally between the bearingsf with a pulley y, connected by a belt ,2 with the pulley on thedrive-shaft h. On one end of the shaft 9 a rotary cutter-head 15 (seeFig. 2) is secured. Said head is provided with a series ofperipherally-arranged shaping-blades 16, having V-shaped cutting-edges17. (See Fig. 2.) The bodies of the blades 16 are slotted longitudinallyat 18 (see Fig. 3) and adjustable radially on the inner face of the head15 by means of screw-bolts 19 and nuts 20. The flange 21 on said headserves to properly center said knives. Rand-knives 22 are secured to theface of the head 15 by screws 23, said knives being arranged toalternate with the shaping-knives 16. The rand-knives have bevelededges, as best shown in Fig. 3. A rod 25 (see Fig. 2) is arranged at therear of the machine parallel with the shaft g, and a gage mechanism 0 ismounted at each end of said rod, said mechanism comprising a sleeve 26,adjustable by a set-screw 27 on said rod, from which an arm 28 projectslaterally at right angles to the shaft g. A rod 29 is fitted to slidelongitudinally in a sleeve 30, formed centrally on said rod 28 andsecured therein by a nut 31. Said rod 29 bears on its inner end astationary guide-cap 32, which is adapted to inclose or partiallyinclose therotary cutter-head 15. The walls of the cap 32 convergeinwardlyat 33, and an annular flange 34 is formed at the mouth thereof,said flange being provided iuteriorly with an annular rabbet 35. Thebody of the cutter-head 15 ispe'veled at 36 to center in said cap. Theouter end of the rod 28 is provided with a sleeve 37, in which a bar 38is adjustable longitudinally by means of a set-screw 39, said barbearing a segmental guard-plate 40, which engages the outer face of thecap 32. By releasing the rod 29 in the sleeve 30 the cap 32 may be movedforward onto the cutter-head to get said rod into alignment with theshaft g, where it is set by the nut 31. The knives 16 and 22 enter therabbet 35 on the cap 32, and the cutting-surface of their blades may nowbe ad- 10 justed by moving the gage O on the rod to expose the desiredportion of said blades, particularly of the rand'knife 22 and securingit by means of the set-screw 27.

In Fig. 8 the pattern D is shown with the x5 sole-stock E securedthereto. The body of the pattern 45 consists of a sheet of metal cut inthe desired shape, to each face of which a wooden block 46 and 17 isrespectively secured. Said blocks follow in outline the shape '20 of thepattern, but are less in diameter than said pattern, the space 48between the edge of the pattern and the edge of said blocks being equalto the depth at 49 of the flange 3 1 from the outer face of the cap 32.The

2 5 stock E is attached to the blocks 46 or 47 in the ordinary manner ofsecuring sole-stock to a pattern and projects beyond the edge of saidpattern, leaving a space 50 between said stock and pattern which isequal in breadth 0 to the breadth of the flange 3 1 on the cap 32. Inuse, the cap 32 being adjusted over the head 15, the operator holds theedge of the pattern 45 against the side 49 of the flange 34, said flangeentering the space 50 between the pattern-body and stock E. The stockthus comes into contact with the knives 16, which reduce it to the shapeof the pattern, the edge of the pattern-body being turned and held inengagement with the face of the cap 32 by the operator.

For cutting an outer sole a straight-edged knife is employed instead ofthe V-shaped knife 16; but when it is desired to shape flexible innersoles such knives turn the edges on the inner sole WltlZOlll] cutting.To obviate this I employ the V-shaped blade, the opposite edges of whichstand at an angle to the sole-edge, and draw-cut said edge toward thecenter, preventing the sole from turning.

Several of said flexible soles may be cut at the same time. \Vhen solesare shaped by rotating knives, as described, a thin rough or featheredge is left on the grain side of the leather. To remove this edge thebeveled rand-knives 22 are employed, the cut of said knives being gagedby the overlapping of the cap 32. Adjacent to the cutter-head 15 atreadle-actuated chamfering or facing cutterhead II is splined on theshaft g. The head H is provided on its working face with a series ofradiallyarranged straight-edged knives 51, behind which openings 52 areformed through the body of the head for the shavings. Segmental openings53 (see Fig. 5) are also ,6 5 formed in said head to receive the blade16 on the cutter-head 15 when the chamfering-head is forced forward byits treadle mechanism. The working face of the head His beveled at 54.(See Fig 6.) Said head comprises a body portion 55, in which thespline-slot 56 is formed, and a sleeve 57, which is adjustablelongitudinally on said body and is secured by a set-screw'58. The knives51 are secured to the body portion 55 by screws 56. By moving the sleeve57 on said body the out of said knives may be gaged. The treadlemechanism for said head comprises a bellcrank lever 60, pivoted to thestandard-head d. To one arm of said lever a bar 61 is pivoted, its upperend being pivoted to a ring 62, encircling the body of the head H. Tothe opposite end of the lever 60 a rod 63 is pivoted and connected atits lower end with an ordinary foot-treadle 64. The rod 63 is screw?threaded at 66, and nuts 67 are turned thereon on opposite sides of anarm 68 on the standard A, through which said rod 63 passes. By adjustingthe nuts 67 the treadle movement in throwing the head II may beregulated. In use when the sole-stock is secured to the pattern thegrain side is in engagement with the edge of the cap 32. By forcing thehead II against the flesh side of said sole the edge may be faced orchamfered by the knives 51, conjointly with the shaping of the sole bythe cutter-head 15. For featheredging the soles a similar cutter-head His mounted on the opposite end of the shaft g. In the gage O at this endof the shaft the guard-plate 400 is pushed by a spring 70, its rod 38sliding in the sleeve 37 of the gage. The cutter-head 15 is omitted fromthis end of the shaft and inclined feathering-blades k (shown in Fig. 7)are substituted for the blades 51 on the head H. The inclinedcutting-edge 71 of said blade bevels or featheredges the edge of thesole, and said blades are provided with an angular cutting-flange 72,which forms a channel-shoulder on the sole at the inner edge of saidbevel. When the sole has been shaped and faced by the cutter-heads 15and 'H, it is disposed between the spring-pushed guard 400 and thecutterhead H forfeather-edging, as described. The leather shavings andother refuse falling from the cutter-heads are received by the hoods 2;and drawn into the pipe-mouths w by the suction-fan B, from whence theyare ejected through the discharge :0.

Having thus explained my invention, what I claim is 1. The shaft g andactuating mechanism, in combination with the non-rotating guide-cap IIOhaving an outwardly-flaring inner wall and adjusting mechanism therefor,a treadle-actuated cutter-head splined on said shaft and beveled at itsfront end to center within said cap, and radially arranged facing-knivesthereon, substantially as described. 7
